A pitch actuation system for a turbine engine propeller, comprising an actuator, a movable part of which is designed to be connected to blades of the propeller so as to rotate said blades relative to blade pitch-setting axes, wherein the actuator is an electromechanical actuator and comprises at least two electric motors for driving a common rotor, and a transmission screw rotated by the common rotor, and in that the system further comprises a nut, through which the transmission screw passes and which is designed to cooperate with the blades so as to move them.
